Peregrine Active Protection System

Armoured vehicle improvement

The project aimed to provide a solution that mitigates the threat posed to military vehicles by shoulder-launched anti-armour weapons, such as the Russian RPG-7. These weapons use a class of projectile known as the High-Explosive Anti-Tank (HEAT) round. Making use of a shaped charge design, the warhead can penetrate Rolled Homogeneous Armour anywhere in thickness right up to 750mm (round dependant). No vehicle armour is sufficient enough to guarantee full protection to the crew, which is why many use an add-on known as bar armour. Despite increasing the crew and vehicle's protection, it is far from fool proof which is why many armed forces are now looking for alternative solutions. This concept makes use of a high velocity jet of water to deflect the head of the projectile away from the vehicle, preserving the lives of the crew inside.
